Abstract
A novel methodology was developed for indirect determination of the mechanical parameters of the oxide in reinforced concrete corrosion, with satisfactory results. It combines accelerated corrosion tests performed over concrete prisms cast around a steel tube equipped with special instruments, and numerical simulations using a model that reproduces the oxide expansion and its mechanical behavior, and fracture of concrete by means of the cohesive crack model. In this work, systematization for determining the values of the oxide parameters is proposed, and strong verification of the method is provided by presenting the results of an extensive experimental campaign.
